At re:Invent in December, Amazon announced the AWS Graviton2 processor and its forthcoming availability powering Amazon EC2 M6g instances. While the first-generation Graviton processor that powered A1 instances was better suited to less compute-intensive workloads, this processor is intended to offer AWS customers a compelling alternative to conventional x86-powered instances on both performance and cost.
Scylla is an open source database alternative to Apache Cassandra, built to deliver significantly higher throughput, single-digit millisecond latency, and always-on availability for real-time applications. Unlike Cassandra which is written in Java, Scylla is implemented in C++ to provide greater control over low-level operations and eliminate latency issues related to garbage collection.
Identity and access management (IAM) in AWS is a way to grant access to AWS services and collect and transmit data and credentials. Most Kubernetes “Quick Start” guides for AWS do not adequately cover how to manage IAM access in your pods. This blog series will first go over the security issues specific to AWS IAM on Kubernetes, then compare solutions, and then we will end with a detailed walkthrough for setting up your cluster with one of those solutions.
In Part 1 of this series, we demonstrated how to enable PSPs in Rancher, using restricted PSP policy as default. We also showed how this prevented a privileged pod from being admitted to the cluster. Enforcement capabilities of a Pod Security Policy We intentionally omitted particular details about role-based access control (RBAC) and how to link pods with specific PSPs. Let’s move on and dig in more on PSPs.
Telemetry is the collection of measurements or other data at remote or inaccessible points and their automatic transmission to receiving equipment for monitoring. In network telemetry, network devices such as routers, firewalls and switches push real-time data continuously to one or more centralized locations for storage, processing and analysis.
Gunicorn is a popular application server for Python applications. It uses the Web Server Gateway Interface (WSGI), which defines how a web server communicates with and makes requests to a Python application. In production, Gunicorn is often deployed behind an NGINX web server. NGINX proxies web requests and passes them on to Gunicorn worker processes that execute the application.
Today, we announced our $40M funding round led by Telstra Ventures. We have been working with Telstra as a customer for many years. When Telstra Ventures, who was familiar with Telstra’s success in using Rancher and Kubernetes, approached us for a potential funding round, it was a no-brainer. A leading telco like Telstra exemplifies Rancher’s vision to Run Kubernetes Everywhere.
Netdata contributors have greatly influenced the growth of our company and are essential to our success. The time and expertise that contributors volunteer are fundamental to our goal of helping you build extraordinary infrastructures. We highly value end-user feedback during product development, which is why we’re looking to involve you in progressing our machine learning (ML) efforts!
This blog post is an adaptation of a talk I gave at the Cloud Native meetup in Birmingham in the UK in February 2020. It details the advantages of k3s, a lightweight Kubernetes distribution we have deployed as part of a managed Kubernetes service. Developed by Rancher Labs, k3s allows for quick deployments for testing, CI/CD runs and getting to grips with Kubernetes without having to commit to large-scale infrastructure and the costs that would bring.
